Title: Air bubble detector
Inventor: KOTOU HARUHIKO
IPC: G01N27/06
Filed: 1980-06-06
Abstract: PURPOSE:To accomplish the detection of air bubbles in an ink passage accurately regardless of attitude of the device by arranging a plurality of electrodes in the ink passage and a tubule between electrodes in an ink jet recorder. CONSTITUTION:As ink 25 is consumed, air 24 flows into a cartridge 18 through an inlet 24. For some reasons, the air bubbles may flow into a printing head from a porous member 23 and reaches a tubule 20. The internal surface of the tubule 20 is so smooth with a hydrophobic property that the air bubbles are formed in a cylindrical form thereby creating a space completely free of ink 25. As a result, the resistance value between the electrodes 21 and 22 becomes infinite. Thus, if the printing is halted by detecting changes in the resistance value, the inflow of the air bubbles into the head 11 can be prevented.
